    Objective: To determine the effect of three pigmenting solutions on the color stability of stock acrylic teeth for prostheses in vitro. Methodology: The research was experimental, using 80 Olympic acrylic teeth, divided into four experimental groups of 20 teeth each, with each group exposed to one of the pigmenting substances: coffee, carbonated beverage, red wine, and distilled water (the control group). The statistical test used was ANOVA to assess differences between groups, and for multiple comparisons, the Tukey and Duncan tests were applied with an error margin of 0.05. Results: Coffee was the pigmenting solution that caused the most significant chromatic variation in Olympic acrylic teeth, with an average variation of 3.56, followed by red wine with an average variation of 2.12, carbonated beverage with 2.06, and distilled water with an average variation of 1.50. Conclusion: Coffee was the pigmenting solution that caused the most significant chromatic variation in Olympic acrylic teeth, followed by red wine, and finally, the carbonated beverage.
